Application March 24,1948, Serial No. 16,758 8 Claims. (C155-3511) This invention .relates .to lnew :and .useful improvements .inLaispring vassembly mattress .andlmethod for making the same, and has particularreference toafspring'assembly `providing a support for ,padding 4or :upholstery to be carried by said assembly, `whereby .fsaid padding or -upholstery .is .prevented 7from working into fthe .spaces withinand between thecomponentsprings.

The principal purpose of this inventionfis the provision,

.parallel .rows with .the .adjacent bottom loops of .corresponding on the .upper .surface `of said assembly, said padding support fcomprising a plurality extending over the surface of said `assembly .transversely ofsaidlbindercoilsand provided with transversely .extending portions at .said 'binder coils, said transversely extending 'wire portions extending through -one `or more l.of vthe convolutions of said binder =.coil, iwhereby said padding support `wires are retained in Isu'b- .stantially flixed` relation relative to the spring assembly.

A.Other lobjects :are :simplicity :and economy 'of fconstru'c tion, .andzea's'e of iassenibly.

`With 4.these .objects Ain view, .as well .as other objects which will:appear'in the conrse1ofthe spe`cit'cation,1refer -`ence `will be had tol the drawing, wherein:

Any number-of springs may, of course,

.be .used depending on the size of the spring assembly to 'be built. The top 'loops I2 'springs lie in substantially 'horizontal lplanes which will 'hereafter be designated respectively the .upper and lower and 'bottoniloops -14 `of said marginal edges of the spring assembly thus formed are bound by helical binder coils of relatively small diameter, binder coils i6 being coiled about the outer portions of the top and bottom loops of springs 10 at each end of the spring rows, and binder coils 18 being coiled about the outer portions of the top and bottom loops of springs 10 in each of the outer spring rows. The end loops of adjacent springs in each of thel spring rows overlap slightly, and are joined together by binder coils 20, which extend in parallel relation transversely to the spring rows and join the overlapping portions of the end loops of corresponding springs in each of the rows. Each of closed in Figs. `1 and 2,

2,740,134 Patented Apr. 3, 1956 Vcoils 16, .18 and Z0 :is securely anchored in' place by havsaid wires is :formed'to `present a' plurality 'of spaced 'apart parallel reaches 24parallel to the spring rows and extending between a pair-of adjacent bindercoills 20, or between a binder ,coil 20 yand .a marginal binder coil V16. Said parallel reaches are 4joined by transversely extendingconnecting portions 26, said connecting portions being disposed axially within 'one'ofih'e binder coils and extending through one or more full convolutions thereof. By'thus positioning the connecting .portions 26 of wires 22'within said binder coils, said Wires are held securely relatively `to the spring assembly. The end portions of 'wires 22 may be anchored by looping them aroundV a convenient loop-of oneof the bindercoils,'andwrapping them around ythe :top loop aofone'of `springs 10. The distance between the parallel reaches24 of the support wires is suiciently 4small to be effective in `preventing the padding of the mattress from working into the spaces within and between springs .10.

.transversely extending portions 32 therefore being `disposed in :alternate binder coils 20. in .the modification shown in Fig. y4, .padding support wires '34 extend in substantially parallel relation across the spring assembly transversely to binder coils 20,

b inder rc oils 16, -as atiZ. Each of said support .wires vis zig-zag 1n form, being transversely oiiset .in 'the same :direction ateach of binder coils 20, and having said transverse oiisetportion-dd disposed axially in said binder coil.
